The molecular weight of Aluminum triacetate [Al(CH3COO)3] is 204.1141384.

Aluminum triacetate [Al(CH3COO)3] is an organic compound of four elements: Aluminum, Carbon, Hydrogen, and Oxygen. The molecular weight of Aluminum triacetate is 204.1141384 which can be calculated by adding up the total weight (atomic weight multiplied by their number) of Aluminum, Carbon, Hydrogen, and Oxygen.

# CALCULATION PROCEDURE: Aluminum triacetate [Al(CH3COO)3] Molecular Weight Calculation

Step 1: Find out the chemical formula and determine constituent atoms and their number in an Aluminum triacetate molecule.
You will know different atoms and their number in an Aluminum triacetate molecule from the chemical formula. The chemical formula of Aluminum triacetate is [Al(CH3COO)3]. From the chemical formula, you can find that one molecule of Aluminum triacetate has six Carbon (C) atoms, nine Hydrogen (H) atoms, six Oxygen (O) atoms, and one Aluminum (Al) atom.

Step 2: Find out the atomic weights of each atom (from the periodic table).

Atomic weight of Carbon (C): 12.0107 (Ref: Jlab-ele006)
Atomic weight of
Hydrogen (H): 1.008 (Ref: Lanl-1)
Atomic weight of Oxygen (O): 15.9994 (Ref: Jlab-ele008)
Atomic weight of Aluminum (Al): 26.9815384 (Ref: ciaaw-aluminium)

Step 3: Calculate the total weight of each atom in an Aluminum triacetate molecule by multiplying its atomic weight by its number.

Number of Carbon atoms in Aluminum triacetate: 6
Atomic weight of
Carbon (C): 12.0107
Total weight of Carbon atoms in Aluminum triacetate: 12.0107 x 6 = 72.0642

Number of Hydrogen atoms in Aluminum triacetate: 9
Atomic weight of Hydrogen (H): 1.008
Total weight of Hydrogen atoms in Aluminum triacetate: 1.008 x 9 = 9.072

Number of Oxygen atoms in Aluminum triacetate: 6
Atomic weight of Oxygen (O): 15.9994
Total weight of Oxygen atoms in Aluminum triacetate: 15.9994 x 6 = 95.9964

Number of Aluminum atoms in Aluminum triacetate: 1
Atomic weight of Aluminum (Al): 26.9815384
Total weight of Aluminum atoms in Aluminum triacetate: 26.9815384 x 1 = 26.9815384

Step 4: Calculate the molecular weight of Aluminum triacetate by adding up the total weight of all atoms.

Molecular weight of Aluminum triacetate: 72.0642 (Carbon) + 9.072 (Hydrogen) + 95.9964 (Oxygen) + 26.9815384 (Aluminum) = 204.1141384

So the molecular weight of Aluminum triacetate is 204.1141384.
